There were any of the following features:
The seizure lasted for more than 15 minutes, or
There were focal features during the seizure, or
recurred in the same febrile illness, or within 24 hours, or
incomplete recovery after one hour.
The child has no serious clinical findings but is currently taking antibiotics or has recently been taking them.

ABCDE recovering position infer over >5-10mins MIDAZOLAM infection source find if suspecting mengitis do LP
advice to parents of feb fit
reasurrance protect head do not restrain or put anything in mouth remove nearby danger very common high temp causes it- no longstanding brain damage not same as epilepsy and doesn't increase risk -very mariginaly different antipyrexical don't help 1-3 another episode
acute management if happens again-undress. give paracetamol, fluid intake, fan
< 5 mins seek help
When the seizure stops, check their airway and place them in the recovery position.
If the seizure lasts more than 5 minutes give:
Rectal diazepam repeated once after 5 minutes if the seizure has not stopped, or
One dose of buccal midazolam.
doses of rectal diazepam
ecommended doses of rectal diazepam (repeated after 5 minutes if necessary) are:
Less than 1 month of age: 1.25–2.5 mg.
1 month–1 year of age: 5 mg.
2–11 years of age: 5–10 mg.
mizadolam doses
Midazolam may be given as a single dose by the buccal route (intravenous solution for injection should be administered into the buccal cavity between the gum and cheeks using a syringe or straw), although it is not licensed for this indication. Recommended doses of midazolam are:
Less than 6 months of age: 300 micrograms/kg body weight (maximum 2.5 mg).
6 months–11 months of age: 2.5 mg.
1–4 years of age: 5 mg.
5–9 years of age: 7.5 mg.
when to call ambulance with feb fit
all an emergency ambulance if, 10 minutes after the first dose:
The seizure has not stopped.
The child has ongoing twitching (although the larger jerking movements have stopped).
Another seizure has begun before the child regains consciousness.
Measure blood glucose if the child cannot be roused or is convulsing.
nice guidelines about parental advice with feb fit
Inform parents about the nature of febrile seizures:
Febrile seizures are not the same as epilepsy. The risk of epilepsy developing later is low but slightly higher than the general population.
Short-lasting seizures are not harmful to the child.
About 1 in 3 children will have another febrile seizure.
Advise parents on what to do if a further seizure occurs. They should:
Protect them from injury during the seizure.
Not restrain them or put anything in their mouth.
Check their airway and place them in the recovery position when the seizure stops. Explain that the child may be sleepy for up to an hour after the seizure.
Seek medical advice if a seizure lasts for less than 5 minutes, or call an ambulance if the seizure continues for more than 5 minutes.
Advise parents about managing fever, but explain that reducing fever does not prevent recurrence. Advice should cover:
When and how to use ibuprofen and paracetamol to reduce fever.
Practical measures on how to reduce fever and prevent dehydration.
When to seek medical help because of prolonged symptoms, or deterioration, especially if there are features of a serious underlying cause for the infection, such as meningitis.
For further information see the CKS topic on Feverish children - management.
Advise parents to continue childhood immunizations even if the febrile seizure followed an immunization.
Do not prescribe drugs to manage or prevent future seizures unless advised to do so by a specialist. This may be advised following assessment of a child with an indication for urgent admission.
Arrange follow-up, the timing of which will depend on the clinical condition of the child.
what is a breath holding attack
how long
infant usually or toddler is upset angry or scared they tend to be trigged by trauma or anger can be caynatoic appear to stop breathing on exhalation its involuntary lasts less than. 1min
episodes include
BHA
prolonged crying and bread held can lead to cynaosis
grow out by 5 years usually 6 to 18months
F=M
two types of BHA
cyanotic and pallid spells
describe each bHA
cyanotic preceipated by crying very upset deep breath cyanotic limb extend may be stiff or floppy cn become unconscious for less than a min involuntary not dangerous breathing resumes after a gasp
what Does it increase risk of later on with BHA
vasovagal attacks
